This paper represents the criteria of earthing system for substation design in Korea. The construction of new substations and expansion of existing facilities are commonplace projects in KEPCO(Korea Electric Power Corporation). The KEPCO has had the only design criteria, which need to be adequate criteria considering the new technology and environment in Korea.

This paper represents the step response characteristics of shunts for impulse current. This work is aimed at the development of the reference measuring system(RMS) for impulse current rated 10 ㎄ at 1/20 ㎲, 100 ㎄ at 4/10 ㎲, 20 ㎄ at 8/20 ㎲, 40 ㎄ at 30/80 ㎲. According to the IEC 60060-2, the step response characteristics was assessed. As results of the test, the step response characteristics of newly developed shunts for impulse current satisfied requirements of RMS.
